Preparation of Palladium-Impregnated Ceria by Metal Complex Decomposition for Methane Steam Reforming Catalysis

Figure 6

Pd 3d XPS profiles of the Pd-impregnated ceria catalysts. (a) 3Pd-CeO2-T-Cl, (b) 3Pd-CeO2-T-N, and (c) 3Pd-CeO2-B-N. The green and blue lines represent the decomposed spectra which could be assigned to the oxidized Pd species of Pd²⁺ and Pd^δ+ (δ > 2), respectively. The red line represents the combination of all decomposed spectra of Pd 3d.
